Is Your Electrical Panel Dangerous?

If you live in Cle Elum, Ellensburg, or Wenatchee, chances are your home has some history. That’s part of the charm—but it also means some electrical systems are… well… seasoned. One of the most important things to keep an eye on? Your electrical panel.

Your panel is basically the traffic cop for all the electricity in your house. When something goes wrong—too much power on a circuit, for example—it should “trip” the breaker to stop the flow and keep you safe. But some older panels don’t always do their job, and that’s where things can get dangerous.

Why Certain Panels Are a Problem

There are a few specific brands and models that have earned a bad reputation among electricians:

• Federal Pacific Electric (FPE) Stab-Lok – Installed from the 1950s through the 1980s. Known for breakers that sometimes fail to trip when they should—tests have shown failure rates as high as 1 in 4. That can lead to overheating, electrical fires, or damage to your appliances.

• Zinsco / GTE-Sylvania – Popular in the 1960s and 70s. These have metal parts that can corrode or even fuse together. When that happens, the breaker might look switched off but still be sending electricity through the wires. That’s as dangerous as it sounds.

• Challenger – Installed mainly in the 1980s and 90s. Some models (especially certain breaker types) have a history of overheating or failing to trip.

The big issue with all of these? They don’t reliably shut off power when there’s a problem—which is the whole point of having them in the first place.

How to Tell if You Might Have One

You don’t have to be an electrician to do a quick visual check. Here are some homeowner-friendly clues:

• Look for the brand name – Open your panel door (no tools needed) and check the label on the inside. If it says Federal Pacific, FPE, Zinsco, Sylvania, or Challenger, it’s worth having a pro inspect it.

• Colorful breakers – Brightly colored breaker handles (red, blue, green) are a giveaway for older Zinsco models. If your breakers look like a pack of Skittles, it’s probably time for a replacement.

• Red stripe handles – FPE Stab-Lok breakers often have a thin red line running across the handle.

• Signs of heat or wear – Rust, dark discoloration, a melted look around breakers, or a panel that feels warm to the touch are all red flags.

Why This Matters in Central Washington

In our service area, it’s not unusual to find these outdated panels still in homes—especially if your place was built or last updated between the 1960s and 1990s. Many of these panels were installed when the house was built and have never been replaced.

We still see them regularly in Cle Elum cabins, Wenatchee ranch houses, and Ellensburg family homes. Just because “it’s been fine so far” doesn’t mean it’s safe.

What Happens if You Keep One

A faulty panel can cause:

• Overheated wires that could start a fire inside the walls.

• Appliances wearing out faster because of inconsistent power.

• Electric shocks in rare but serious cases.

• Trouble with your home insurance—some companies won’t insure homes with certain panel brands.

What to Do if You Suspect You Have One

1. Don’t panic – You don’t need to shut down your whole house today, but you do want to act sooner rather than later.

2. Call a licensed electrician – We can confirm the brand and condition of your panel, and let you know if it’s a replacement situation.

3. Consider upgrading – A new panel from a reliable brand (like Eaton, Square D, or Siemens) is safer, meets modern code, and may even help with insurance.

4. Skip the DIY – Anything involving your panel is not a weekend project. The risk isn’t worth it.
